I assumed that Maryland is referring to an Aiwa FM stereo cassette and CD player like a boombox that that has an auxillary input. Most of this auxilliry jack at the back are RCA female. Even in the stereo component. If she's using a stereo component like an A/V receiver most common in a sorround sound system, a separate tape deck is also connected to RCA female input. All audio input/output should all be female and this is standard in electronic technology. Now, if Maryland is trying to hook up a separate tapedeck this cable can also be use to connect to its input if it has a built-in amp.
